3.1 Behind IP-Sharing

3.1.1 IP Sharing Configuration

3.1.1.1 One VoIP Gateway behind VoIP Gateway
This application is only for the user who is using the IP Sharing device, and the
VoIP gateway is connected behind the IP sharing device. The IP Sharing Device
must support the DMZ or Virtual server functions such as ADSL network.
Step 1. The WAN IP Address obtained from ADSL has two kinds of methods. One is
fixed IP Address, while user applies for one or more fixed IP Addresses.
Another is dynamic IP Address while user applies for dial-up connection way.
Only when the IP address is fixed, user can put the gateway behind NAT
device.
Step 2. The LAN IP Address of User's PC can be set as DHCP client in order to gain
a valid one.
Step 3. One can also assign a fixed IP address, which belongs to the same network
segment as the LAN interface of IP Sharing device.
Step 4. VoIP Gateway must enable the IP Sharing function for the fixed / dynamic
WAN IP Address.
Note:
With Dynamic WAN IP Address, a valid Proxy for the Gateway to get register on
is a must. In other word, it is not workable in Peer-to-Peer mode while dynamic
WAN IP Address.
Step 5. IP Sharing device must have a function to do IP/Port mapping. Some is
named as DMZ, some is named as virtual server. The VoIP messages from
WAN have to completely pass forward to the LAN. It means that if the
Gateway is assigned a virtual fixed IP Address such as 192.168.1.5, IP
Sharing device must forward the VoIP message to 192.168.1.5.
